The RAID array houses one 2.5″ SSD in each bay and is generally preconfigured in RAID 5 but supports RAID 0, 1, 10, and 50. It can provide transfer speeds up to 2800 MBps using the Thunderbolt 3 interface and can be used with USB 3.2.
RAID 6 is one of the most commonly used levels of RAID (Redundant Array of Independent Disks) in use today. RAID is a disk management solution for hardware arrays of data storage disks.
So the big problems for conventional RAID groups are (1) as the drives get larger, the number of drives in a RAID group needed to encounter a URE, decreases (true for both RAID-5 and RAID-6 groups), and (2) the rebuild times are getting extraordinary long because read and write performance stays the same but the RAID groups have more data.
RAID Controllers The acronym RAID stands for redundant array of independent disks. A RAID system may be hardware or software, and virtualizes physical storage drives to improve performance and create data redundancy.
The most commonly seen of these are RAID 0, RAID 1, RAID 5, RAID 6 and RAID 10. Each of these configurations makes use of a different strategy for duplicating data and ensuring that it is not lost or damaged.
RAID offers greater access speed, data security, and overall fault tolerance over single disk configurations, and RAID 10—a combination of RAID levels 0 and 1–brings even better performance. This guide covers what RAID 10 is, how it works, and how it compares to other RAID levels. What is RAID 10 and How Does it Work?
RAID enables the same data to be saved across multiple disks while still appearing as a single logical drive using specialized hardware or software called a RAID controller. RAID levels, which are denoted by a number, determine the performance characteristics of a given configuration and how much or little data protection they offer.
For instance, if we have a RAID-6 group with 10 total drives and you lose a drive, then 100% of the seven remaining drives have to be read to rebuild the failed drive and regain the RAID-6 protection. This is true even if the file system using the RAID-6 group has no data in it.
